Create Array Align Close Selected Figures Reverse Line Direction

Transform | Close Selected Figures closes open polylines or polycurves (i.e. the last point of the object is dragged over the first point of the object). This allows them to be filled. You can achieve the same effect manually by dragging the handle of one of the endpoints of the line over the other endpoint, but this function can be more convienent.
